PACKING-RING.

To all whom it may concern Be it known that I, JOHN F. KY'rLicA, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and

State of Illinois, have invented certain new and useful Improvements in Packing-Rings, of which the following is a specification. My invention relates to packing rings such as are used upon piston heads and the like'and has for its object the production of. a packing ring which, when. in use, will be adapted to establish a tight connection be tween the piston head and the cylinder in which the same is operated by effectually preventing leakage through the joints at the. ends of the sections of which the ring is composed.

A further object is the production of a packing ring as mentioned which will be of simple and economical construction and efficient in use.

Other objects will appear hereinafter. With these objects In view my invention .consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming. a part of. this specification, and in which I Figure 1 is a front elevation of'a packing ring embodying. my invention, Fig. 2 is a section taken on line a:a: of- Fig. 1, Fig 3 is a bottom; lan'view of Fig. 2, Fig. 4 is a plan view of one of the Sections of the packing ring, and Fig. 5 is a fragmentary perspective of thesection shown in Fig. 4.

The preferred form of construction as illustrated in the drawing comprises a packing ring consisting of inner and outer annular split sections 1 and 2 respectively, said sections being formed of spring metal so as to permit of the same being expanded in ordei' to slide the same over the piston head into engagement with the annular grooves usually provided in the piston head for the receptionof the packing rings. After being arranged in position in the moves in the piston head the resiliency 0 said sections 1 and 2 serves to press the latter outwardly into engagement with the walls of .the cylinder in order to establish a tight con nection as is readily understood by those skilled in the Said sections fitone with- 66 in the other as shown, the section\1 being Specification of Letters, Patent.

provided at one edge with an outwardly turned annular radial flange 3 and said section 2 being provided at one edge with an inwardly annular radial flange 4. The flange 3 registers as shown with the un- 50 flanged edge of section 2. Provided at the oppositeedge of section 1 is a longitudinally extending annular flange 5 which registers" with the inner edge of the flange 4, the outer edge of flange 5 being flush with the correa5 sponding edge of the section 2, as clearly ownin Fig. 2 of the drawing. By providing the longitudinal flange 5 upon section 1 the ga which is formed between the d oining en s of flange at the ends 6 and 6 7 of the section 2 is closed, as clearlyshown in Fig. 3, thereby eliminating the formation of a transversely extending passage at this point-which, when the ring is in use, results in leakage therethrough.

The respective ends 7 and 7 of the section v 1 are overlapped as clearly shown in Figs. 1,

4 and 5 so as to prevent the formation of a transversely extending opening through the ring at the adjoining ends of the flange 3 of 30 said section, it being clear that Without this overlapping constructiona transversely eX-.-' tending opening in the ring would be formed between the ends of said flange which when the ringis in use, would result in leakage. 5 Thus it will be seen that with the construction set forth the joints at the respective ends of the sections or component parts of the ring will be tightly closed. precluding the possibility of leakage through the ring when in use.

Provided in the section 1 midway the ends thereof is an outwardly projecting pin 8.- which is positioned between the ends of section 2 so as to prevent relative rotary movement of said sections, holding the joints -in said sections at diametrically opposite sides .of the ring. The end 6' of the section 2 is notched or cut away at 9 in order to accom modate the pin 8 and so as to permit of the ends 6 and 6' closely adjoining each other when the ring is in use. While I have illustrated and described the preferred form of construction for carryin' my invention into effect, this is capable '0 I06 variation and modification without depart-Z ing from the spirit of the invention. I therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifica- 110 lion-s as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A packing ring comprising two annular split sectioi'is fitting one within the other; an. annular inwardly turned radial flange at one edge of said outer section; an annular outwardly turned radial flange at one edge of said inner Section, said outwardly turned flange registe ing with the unflanged edge of said outer section; and a longitudinally extending flange at the other edge of said inner section registering with the inner edge of said inwardly turned flange, the respective ends of said inner section being slidaoly overlapped, substantially as described.

2. A packing ring comprising two annular split sections fitting one within the other; an annular inwardly turned radial flange at one edge of' said outer section; an annular outwardly turned radial flange at one edge oi said inner section, said outwardly turned flange registering with the unilangcd edge of said outer section; and a longitudinally extending flange at the other edge of said inner section registering with the inner edge of said inwardly turned flange the outer edge of said longitudinal flange being flush with the corresponding edge of said outer section, substantially as described.

3. A packing ring comprising two annular split sections fitting one within the other an annular inwardly turned radial flange at one edge of said outer section; an annular outwardly turned radial flange at one edge of saidinner section said outwardly turned flange registering with the unflanged edge of said outer section; and a lon itudinally extending flange at the other e ge of said inner section registering with the inner edge of said inwardly turned flange, the respective ends of said inner section being sildably overlapped, substantially as described.

lar split sections fitting one within the other; an annular inwardly turned radialflange at one edge of said outer section; an annular outwardly turned radial flange at one edge of said inner section, said outwardly turned fiai'ige regdstering with the unflanged edge of said outer section; a longitudinally extending flange at the outer edge of said inner section registering with the inner edge of said inwardly turned flange, the respective ends of said inner section being slidably overrotary movement of said sections, substantially as described.

5. A packing ring comprising two annular split sections fitting one within the. other; an annular inwardly turned radial flange at one edge of said outer section; an annular outwardly turned radial flange at one edge of said inner section, said outwardly turned of said outer section; a longitudinally extending flange at the outer edge of said inner section registering with the inner edge of said outwardly turned flange, the respective ends of said inner section being slidably overlapped and an outwardly projecting pin secured in said inner section engaging between the ends of said outer section for preventing relative rotary movement of said section, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of 1 two subscribing witnesses.
